Изобретение относитс к области технической механики и может быть использовано дл определени координат центра т жести и веса тел, имеющих продольную ось симметрии .The invention relates to the field of technical mechanics and can be used to determine the coordinates of the center of gravity and the weight of bodies having a longitudinal axis of symmetry.
Известны способы определени координат центра т жести тел, заключающиес в том, что тело устанавливают на две располагаемые на его продольной оси опоры, измер ют давление тела на одну из них и вычисл ют координаты центра т жести.Methods are known for determining the coordinates of the center of a body weight, which consist in that the body is placed on two supports located on its longitudinal axis, the pressure of the body on one of them is measured, and the coordinates of the center of gravity are calculated.
Недостаток известных способов состоит в .том, что дл определени центра т жести тел необходимо предварительно определить вес тела, что требует в некоторых случа х использовани весоизмерительных устройств больщой грузоподъемности.A disadvantage of the known methods is that in order to determine the center of gravity of the bodies, it is necessary to pre-determine body weight, which requires in some cases the use of weight-measuring devices with a large carrying capacity.
С целью упрощени технологии по предлагаемому способу вторую опору перемещают вдоль указанной оси, фиксируют, вторично измер ют давление на первую опору, и по результатам обоих измерений вычисл ют координаты центра т жести тела.In order to simplify the technology of the proposed method, the second support is moved along the specified axis, fixed, the pressure on the first support is measured again, and the coordinates of the center of gravity of the body are calculated from the results of both measurements.
На чертеже изобрал ена схема установки, реализующей описываемый способ.The drawing shows an installation scheme that implements the described method.
Исследуемое тело / устанавливают на опоры 2 к 3, располагаемые на его продольной оси, и измер ют, например, посредством весов 4 давление тела на одну из опор, например опору 2. Носле этого перемещают вторую опору 3 вдоль оси тела на некоторое рассто ние, например в положение 3, вторично измер ют давление на первую опору и, составл уравнени равновеси тела при известных рассто ни х LI и La между опорами, вычисл ют координату X центра т жести С тела и его вес G.The test body / is placed on supports 2 to 3 located on its longitudinal axis, and the pressure of the body on one of the supports, for example support 2, is measured, for example, by means of weights 4. Then, the second support 3 is moved along the body axis for some distance, for example, at position 3, the pressure on the first support is measured again and, having made body equilibrium equations at known distances LI and La between the supports, calculate the X coordinate of the center of gravity C of the body and its weight G.
